“ Roadway” Clearance Time The time between first recordable awareness of an incident (detection/ notification/verification) by a responsible agency and first confirmation that all lanes are available for traffic flow. “Incident” Clearance Time The time between the first recordable awareness and the time at which the last responder has left the scene. Secondary Crashes The number of secondary crashes beginning with the time of detection of the primary incident crash where a collision occurs either a) within the incident scene or b) within the queue, including the opposite direction, resulting from the original incident.

“Blockage Removed” Roadway Clearance Time The time all lanes are available for traffic flow (time stamp rather than duration). “Incident” Clearance Time The time the last responder has left the scene (time stamp rather than duration) and are no longer a distraction to mainline traffic. Secondary Crash? Was “this” crash a secondary crash, Yes or No? Was the primary incident a Crash? Yes or No? Did it involve a first responder? Was a first responder an involved traffic unit, Yes or No?
